Hello guys,
I have a problem with the headlights on an F10.
The story sounds like this.
A friend of mine bought an used f10 525d. VIN: DT99551
The car was RHD but now is converted to LHD(we don`t know who made the conversion).
All good so far. The car was working fine except the front doors switch(still on uk style) and knobs on climate pannel so I tried to code IHKA to reverse the controls left to right(driver knob to controll the pasanger side)
I read FA and changed type code from XB32(UK) to XB31(EU), removed option 812 and added 801.
Then I coded IHKA, JBBF, CAS, FRM(I don`t know why) and KOMBI.
From that moment the headlights are not working, only angel-eyes works and also the buttons for heated seats are inverted. I tried to erase the errors and initialise headlights with Ista+ but no success. Every time it ends with error and nothing happends.

Before that the headlights worked just fine with no errors.

I also tried to put back the original FA and code the same modules but the headlights still don`t want to work. They are starting for 5-6 seconds and then starts to flicker and shuts down.

Any sugestion please?
